hwmon: (sht15) Fix sht15_calc_temp interpolation function
commit 328a2c22abd08911e37fa66f1358f829cecd72e9 upstream.
I discovered two issues.
First the previous sht15_calc_temp() loop did not iterate through the
temppoints array since the (data->supply_uV > temppoints[i - 1].vdd)
test is always true in this direction.
Also the two-points linear interpolation function was returning biased
values due to a stray division by 1000 which shouldn't be there.
[JD: Also change the default value for d1 from 0 to something saner.]
